The fm radio can improve the signal of your network wi

Scientists at Northwestern University in the United States have conducted research into the possibilities of using frequency modulation (FM, radio) as a way to improve wireless networks. Called Wi-FM, the technology seeks to use modulated frequencies as a way to prevent wireless networks from having any interference to dips, allowing higher stability and data transfer speeds in these networks.

FM Radio

A common Wi-F signal can experience obstruction and interference caused by broadcasts from neighboring routers. A spectrum of scenario full of Wi-Fi signals, with information packets end up blocking the other and the result ends up being slower with time to surf the Internet.

Aleksandar Kuzmanovic, professor of electrical engineering at the university, gives an example of the phenomenon ", many people just get mad at their routers, but in reality what happens is that the neighbor is watching Netflix."

Wi-FM corrects this problem by using a system that monitors the noise level in the surroundings. This allows a technology-enabled router to send data packets to connected devices only when it detects ideal times, where contamination decreases, ensuring that data will arrive without interference from users.

Apparently, the idea seems to suggest that the system would create a delay, since the router would have to forward the data to be interrupted. However, these lapses are too short, according to scientists, to be imperceptible. The advantage of FM radio is that these frequencies are very easy to pass through walls and other physical obstacles, something that is always a problem for conventional Wi-Fi networks.

Another advantage of technology is the fact that a large part of today's smartphones have antennas and FM radio, which would facilitate an eventual disclosure of this communication standard.

Although the technology is available and relatively cheap to implement, there is still no information on the commercial use of Wi-FM.
